MECHANICALMOVEMENT AND DEVICE.

Specification of Letters Patent.

Patented Apr. 1, 1919.

Application filed April 23, 1917. SeriaLNo. 163,926.

To all whom it may concern: r

Be it known that 1, CHARLES F. Hovnu, a citizen of the United States, residing at Conrad, in the county of Teton, State of Montana, have invented certain new and useful Improvements in Mechanical Movements and Devices; and I do hereby declare the follow ing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in mechanical movements and devices.

One object of the present invention is to provide a novel and effective device which is adapted for different purposes, such as elevating conveyers, or the like.

Another object is to provide a device of this character in which the lifting force is practically or nearly neutralized, thereby greatly facilitating the operation of the device.

Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

In the drawing:

Figure 1 is a side elevation of the device.

Fig. 2 is a transverse sectional view taken 011 the line 2-2 of Fig. 1.

Fig. 3 is a sectional detail of one end of the deviceillustrating the position of the rack member with respect to the shaft.

Fig. 4 is a section on the line 41 of Fig. 1, looking in the direction of the arrow.

Referring particularly to the accompanying drawing there is shown a supporting frame which includes the uprights 10 and 11, the former of which are of greater length than the latter. as-clearly shown in the drawing. A base 12 is provided on which the uprights are supported, and carried by the uprights 10, at the upper end, and supported on the base at the lower end, is an inclined structure 13, short standards being carried by the inclined structure. Mounted on the ends of the inclined structure are the upper and lower transverse shafts 14 and 15, and carried by these shafts, respectively, are the pairs of wheels 16 and 17, the former of which, or the upper ones, being formed on their inner peripheral edges with the shoulders 18, which are smooth, while the latter wheels are formed with shoulders 19 formed with teeth, as shown. Engaged around these shoulders are laterally projecting pins 20 of the endless chain 21. This chain includes the links 22, and on the pins, adjacent the sides of the links are the anti-friction rollers 23 which run on the base on the lower lap of the chain. The ends of the pins engage with the teeth of the lower wheels 17, as shown in the drawing.

Extendingbetween the shafts and supported between the longitudinal strips 24, are the upper and lower rack bars 25 and 26. Between these rack bars and the upper and lower laps of the chain, are the rotatable drums 27, each having around the periphery thereof a series of gear teeth 28 which simultaneously engage with the chain links and with the rack bars. At the lower end of the device there is a curved guard which extends upwardly from the base around a portion of the lower wheels, while a similar curved guard partially surrounds the upper wheels, these guards being shown respectively at 29 and 30. The lower shaft is provided, on one end, with a belt wheel 31 for receiving power from any desired source, and by means of which the device is driven.

It will thus be seen that as the chain travels around the wheels the drums will be caused to rotate by reason of their contact with the chain and the rack bars, and that said drums will also travel between the rack bars and the chain first upwardly and around the upper shaft and then downwardly around the lower shaft.

Cylindrical objects 32, which may be cans, metal bars or other objects to be conveyed, are placed in the drums and it will be understood that the weight of the downgoing ob jects will overcome to a degree the resistance to the operation of the mechanism afforded by the upgoing objects.

This renders the operation of the device easy.

It will be noted that the rack bars are joined at their upper and lower ends by the curved rack sections 25, so as to extend around the respective shafts and permit the free and easy movement of the drums when passing around said shafts.

What is claimed is:

1. A conveyor including a support, paral lel spaced sprockets mounted at the ends of the support, an endless chain engaged around the sprockets, a rack member eX- tending longitudinally between the laps of the chain, open-ended carrier drums disposed between the laps of the belt and the rack member and provide with Ci1?CL1l11f81Q11- tial series of teeth engaging simultaneously With the chain and the rack member and means for driving the sprockets.

2. A mechanical device including an endless driving element, rolling open ended carrier elements disposed Within and contacting with the driving element and a stationary driving element disposed Within the endless driving element and contacting With the 10 rolling elements.

In testimony whereof, I afiix my signature in the presence of a Witness.
